Thanks to the sharp eyes of
headintheclouds a few typos have been found and corrected in the fare conversion spreadsheet. These involve Gibraltar, Latvia, and Lebanon. All the errors were obvious if looking at these countries (e.g. 6 continent fare less than 3 continent, etc.). It is only worth re-downloading the sheet if you are considering one of these countries as an origin.
Sorry for the problems but typing has never been one of my strong suits.
